commit    3b3e8fc9cf395400fb9108b4e384ab9b6bf2ec14
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Mon Dec 28 17:09:00 2015 +0000
First released in: 9.6.0, 9.1.20, 9.2.15, 9.3.11, 9.4.6, 9.5.0

    Document the exponentiation operator as associating left to right.
    
    Common mathematical convention is that exponentiation associates right to
    left.  We aren't going to change the parser for this, but we could note
    it in the operator's description.  (It's already noted in the operator
    precedence/associativity table, but users might not look there.)
    Per bug #13829 from Henrik Pauli.
